Assessment of the prognostic capacity of pretreatment, interim, and post-therapy (18)F-FDG PET/CT in extranodal natural killer/T-cell lymphoma, nasal type.

Objective Although the prognostic value of positron emission tomography/computed tomography (PET/CT) using [18F]-fluorodeoxyglucose (18F-FDG) has been widely confirmed for diffuse large B cell lymphoma, its value for extranodal natural killer/T-cell lymphoma, nasal type (ENKTL), is still controversial. Therefore, we designed a prospective study to investigate the prognostic value of 18F-FDG PET/CT in patients with ENKTL.
